Tappeh Pitti背斜为中伊朗盆地Garmsar区块内地表最完整的背斜构造。通过对Tappeh Pitti背斜地震剖面的精细解释及其形成演化和形成机理等方面的分析和探讨,认为Tappeh Pitti背斜具有深浅不协调的特点,即在浅层表现为一鸡蛋型完整背斜而在深层却表现为一向西倾伏的鼻状构造;Tappeh Pitti背斜定型于第四纪,其成因与上红组M2段内层面滑脱断层有关。

A series of cobalt doped TiO2（Co-TiO2） and Co Oxloaded TiO2（Co/TiO2） catalysts prepared by sol–gel and impregnation methods respectively were investigated on selective catalytic reduction with NH3（NH3-SCR） of NO. It was found that Co-TiO2 catalyst showed more preferable catalytic activity at low temperature range. From characterization results of XRD,TEM, Raman and FT-IR, Co species were proved to be doped into TiO2 lattice by replaced Ti atoms. After being characterized and analyzed by NH3-TPD, PL, XPS, EPR and DRIFTS, it was found that the better NH3-SCR activities of Co-TiO2 catalysts, compared with Co/TiO2 catalyst, were ascribed to the formation of more oxygen vacancies which further promoted the production of more superoxide ions（O-2）. The superoxide ions were crucial for the formation of low temperature SCR reaction intermediates（NO-3） by reacting with adsorbed NO molecule. Therefore, these aspects were responsible for the higher low temperature NH3-SCR activity of Co-TiO2 catalysts.

In this paper, on the basis of the stress field given by ***, three new photoelastic methods are developed for determining the stress intensity factors K1 and K2 of V-shaped notch. Some photoelastic experiments are performed on a skew -symmetric 45° notch. Measurements of the coordinates components of r,θand fringe order N are made for progressively smaller fringes and used in the proposed methods to solve K1 and *** of apparent K vs. r/l are made and extrapolated to the notch tip to yield the true values of K1 and *** results obtained by the three methods are very close to each other. When the notch problem is simplified as a crack problem, the corresponding equation is identical to the one proposed by D.G. Smith, which shows that the proposed methods are applicable for both notch and crack problems.

TiO2 supports doped with different amounts of Si were prepared by a sol-gel method, and 1 wt% vanadia （V2O5） loaded on Si-doped TiO2 was obtained by an impregnation method. The mole ratio of Si/Ti was 0.2, NOx conversion exceeds 94% at 300℃ and GHSV of 41,324 hr-1 , which is about 20% higher than pure V2O5/TiO2 . The catalysts were characterized by XRD, BET, TEM, FT-IR, NH3-TPD, XPS, H2-TPR, Raman and in situ DRIFTS. The results of FT-IR and XPS indicated that Si was doped into the TiO2 lattice successfully and a solid solution was obtained. V2O5 active component could be dispersed well on the support with the increasing of surface area of the catalyst, which was confirmed by Raman and XRD results. Above all, the numbers of acid sites （especially the Br nsted-acid） and oxidation properties were enhanced for Si-doped V2O5/TiO2 catalysts, which improved the deNOx catalytic activity.
